Product Overview
AWS E12015-G low alloy steel electrode is a high-performance welding material independently developed by Hangzhou Lin'an Ocean Welding Materials Co., Ltd. (Ocean Welding), specially designed for 830MPa low alloy steel structure welding. As a low hydrogen iron powder type basic electrode, this product adopts DC reverse polarity, has all-position welding capability, stable arc, less spatter, easy slag removal, beautiful weld formation, excellent X-ray detection performance, and is an ideal choice for key structures such as high pressure vessels, bridges, and marine engineering.
Core advantages: We use advanced testing equipment such as the German Spectro Max spectrometer, and undergo three strict quality inspections from raw materials to finished products to ensure that each batch of products meets the AWS A5.5 standard and ISO 9001 quality system certification requirements.

Application areas
AWS E12015-G welding rods are widely used in the following high-strength steel structure welding:
• Marine engineering: underwater welding structure inspection project of Egypt's Dayang Confidence ship, the weld quality has passed the certification of international classification societies
• Energy facilities: chemical LNG storage tank wall welding, natural gas processing equipment
• Infrastructure: large-span bridge steel structure, high-rise building load-bearing components
• Special equipment: mining machinery, large pressure vessels (design pressure ≥10MPa)
Industry solution: For welding needs in low temperature environments (-30℃), the preheating process of 100-200℃ can be used to ensure that the low-temperature toughness of the weld meets the standard (impact energy ≥47J @ -30℃)

Operation precautions
1. Welding rod baking: bake at 350-380℃ for 1 hour before use, store in 80-100℃ insulation tube for use
2. Workpiece cleaning: remove rust, oil, moisture and other impurities, groove angle recommended 60°±5°
3. Interlayer temperature: control at 150-250℃, clean thoroughly between passes
4. Post-heat treatment: for components with thickness > 25mm, tempering treatment at 600-650℃ for 2 hours after welding

FAQ
Q: What type of welding material does AWS E12015-G welding rod belong to?
A: This product is a low-alloy high-strength steel welding rod with low-hydrogen sodium type coating, which meets the AWS A5.5 standard and adopts DC reverse polarity, suitable for all-position welding. Its core advantages are low diffusible hydrogen content (≤5mL/100g) and excellent low-temperature impact toughness, which is particularly suitable for high-strength steel structure welding.
Q: How long is the shelf life of the product? How to store it?
A: The shelf life of unopened products is 12 months (stored in a dry and ventilated environment, relative humidity ≤60%). It is recommended to use it up within 7 days after opening, and the remaining welding rods need to be sealed and re-baked.
Q: What is the minimum order quantity? How long is the delivery cycle?
A: The minimum order quantity of standard products is 1 ton, and special specifications can be contacted with us. The delivery time for regular orders is 25 days.
